PRINTING STAMP.

Application led August 1G, 1925. Serial No. 49,197.

This invention is for a printing stamp adaptable for use in handmanipulated devices or for machines, and is especially designed for usewith marking devices having l rubber type.

The invention relates especially to a stamp for use in marking shippingcartons and the like.

The invention has for its object to provide al marker of this typehaving readily removable printing` characters which may be easily andreadily interchanged, shifted about, removed and replaced, as desired.

Incidentally, the invention is one that readily lends itself to markingwith two or more colors.

The invention may be readily understood by reference to the accompanyingdrawings, in which:

Fig. 1 is a plan view of a marking device embodying my invention.

Fig. 2 is a longitudinal section in the plane of line II-II of Fig. 1.

Fig. 8 is a partial transverse section.

Fig. l is a schematic view showing the device incorporated in a cartonor other printing machine.

Fig. 5 is a plant view of the adjusting bar at one end of the printingsurface.

Fig. 6 is a transverse section in the plane of line VL-VI of Fig. 5.

In the dra-wings. 5 designates a suitable base plate which is preferablycurved, as shown. This plate may be a complete cylinder, as indicated inFig. t or it may be just a portion of a cylinder, as shown in Figs. 1and 2.

Extending part way across the plate 5 at one end of the printing area,is a fixed strip 6, and at the other end is an adjusting bar or strip 7.Bar 7 may be moved toward or away from bar G by means of suitably argranged set screws or bolts 8 connected with the adjusting bar and with afixed strip r 9, also carried on the base 5. Lock nuts 10 are preferablyprovided on the set screws, l as shown.

Placed on the outer surface of the base plate, between the fixed strip 6and the adjusting bar 7, are one or more, preferably several, rubber orother suitable printing elements. I have shown three such elements, alarge element 11 having a pictorial.

in Fig. 3. The flangesl of the several elements preferably abut, in vthemanner shown.

The printing elements are retained in place by suitable straps 17,preferably .of metal. These straps overlie the flanges of the printingelements, as best shown in Fig. 3, and have hooks at each end thereof.The hook at one end of each strap is designated 17a and engages fixedbar 6. The hook 17", at the other end of each strap, engages theadjustable bar 7. The straps 17 are, of course, recessed from theprinting surface of the printing elements.

With the arrangement as thus described, it is possible to have anydesired number of printing elements. The printing elements need only bearranged on the base, after which straps 17 are applied and screws 8operated to adjust bar 7 to put the straps under considerable tension.As the printing elements are preferably made of rubber,v

the straps will tend to compress the lianges of the elements tofrictionally retain the elements against slippage on the base. Since thestraps act over a curved surface, their efficiency is further increased.

Printing elements may be easily and quickly interchanged, removed, andreplaced,

'and a single base member can be adapted to a great many arrangements.

By removal and substitution of printing elements, the device may bereadily adapted to multicolor printing, as will be understood by thoseskilled in the art.

If desired, graduated markings may be provided along the outer edges ofthe base plate, as shown at 2O to facilitate the positioning oftheseveral printing elements.

In Fig. 4c, I have indicated the base 5 as a cylinder associated withaplaten roller 21, and an inking roller 22, while the article beingprinted is designated 23.

While I have shown a preferred embodiment of the invention, it will beunderstood that various details thereof may be modified and changedWithin the spirit of my invention and under the scopel of the appendedclaims.

I claim as my invention:

l. The Combination with a part cylindrical base having a. fixed crossbar and a relatively movable cross bar at each side ot a printing area,and fixed temper screw abutments beyond the movable bar, otl a pluralityof printing element-s mounted on the base having reduced thicknessretaining flanges, a plurality of retaining straps each having a hookedterminal at each end the fixed cross bar and the movable cross barrespectively and with their intervening portions engaging the retainingflanges of the printing elements, and temper screws mounted in theabutments and engaging the movable cross bar for tightening the strapsover the anges of the printing elements.

2. The combination with .a part cylindrical base having a fixed crossbar and a relatively movable cross bar at each side of a printing area,each having an outwardly disposed il-shaped edge, and fixed temper screwabutments beyond the movable bar, of a. plurality of printing elementsmounted on the base having reduced thickness retaining flanges set edgeto edget a plurality ot retaining` straps each having a V-shapedterminal at each end engaging the fixed cross bar and the movable crossbar respectively, and with their intervening' portions engaging theretaining flanges of the printing elements, and temper screws mounted inthe abutments and engaging the movable cross bar for tightening thestraps over the flanges ot the printing elements.
